THE CHEMAWA AMERICAN
The trout are sent when about two inches long, for liberation in the
streams of the state, in 10 gallon distributing cans holding approximately
1000 each.
There were liberated last year in the various streams in the state 29,
817,851 salmon fry ranging in age from four to eight months. There
were also distributed in the various streams throughout the state 5,723,
726 trout fry.
Last year during the spring run of the Chinook salmon 34,659,000
eggs were secured.
The department of zoology of the Oregon Agricultural College has
been assigned the task of making the young fry so they will be recog
nized when taken by the canneries. It is planned to cut off a portion
of the left pectoral fin and all of the adipose fin.
Salmon fry were liberated in the Willamette, Clackamas. Santiam,
Umpqua and Wallowa rivers. In addition to this 380,500 bluebacks
salmon were liberated in Wallowa lake.
A few miles from Bonneville there is an auxiliary plant on Herman
creek, where. 5,000,000 fry are being cared for.
Hatchery No. 1 at Bonneville is not only the largest in the state but is
the largest of its kind in the world. In addition to the Tanner creek
hatchery at Bonneville, there are in District No. 1 hatcheries atClatska
nie river, on the upper Sandy river, on Salmon river in Idaho, and on
the McKenzie river. At this latter hatchery 13,214,678 salmon eggs
were secured last season.
In district' No. 2 a new hatchery has been built in Tillamook county.
It is located at the mouth of Gold creek where it empties into Trask
river. A hatchery is also located on Elk creek in the Yaquina bay dis
trict. A temporary plant is also operated on Alsea river which is to be
moved to a point two miles above the Tidewater postoffice.
A hatchery is also maintained on the Siuslaw river where considerable
attention is given to the securing of black-spotted trout.
One of the most important hatcheries in this district is located on the
Umpqua river. Last season over 9,000,000 eggs were secured here, most
of which were shipped to Bonneville and other stations.
A hatchery is also maintained at Winchester where steelhead salmon
spawn is secured. Hatcheries are also maintained on South Coos, Co
quille and Rogue rivers. Last season saw a record breaking run of early
Chinook and blueback salmon.
It is believed that the large number of fry of these two varieties liber
ated in 1910 and 1911 from the Bonneville hatchery was responsible for
the heavy run of the past season.
When it is realized that from $5,000,000 to $7,000,000 is derived from
the salmon industry and that nearly 10,000 men are engaged catching,
